Product Description

18crmo4 steel round bar


18crmo4 steel grade is one kind of low carbon Chromium Molybdenum steel material which is usually used to produce 18crmo4 steel joint, 18crmo4 steel nut, 18crmo4 steel screws, 18crmo4 steel shaft, steel stud, 18crmo4 steel flanges and valves etc. SCM420h steel material is in US standard as aisi 4120, sae 4120 and astm 4120. 18crmo4 steel grade equivalent materials includes aisi 4120h, sae 4120h, astm 4120h, 18crmo4,  SCM420 etc.  Except 18crmo4 steel material, there is also 18crmo4 steel material. The difference of 18crmo4 steel and 18crmo4h steel is that 18crmo4 steel is one kind of gear steel which is popular to be used to produce gears and shafts in cars, motors and parts needed strength and cutting features.


Our company is a manufacturer of 18crmo4 alloy steel bar including 18crmo4 Alloy Steel Round Bar, 18crmo4 Alloy Steel Square Bar, 18crmo4 alloy steel flat bar, 18crmo4 alloy Square Steel Bar and 18crmo4 alloy Hexagonal Steel Bar.


Our most popular steel bar sold includes 18CrMo4 polished steel rod / polished steel bar / centerless ground bar / annealed bar / peeled or turned steel bar / Cold Drawn Steel Bar .

6.      Processing of 18crmo4 steel:

We are a factory to process all kinds of steel bars on surface, size and microstructure. With complete production and processing facilities, we can supply all kind of pre heat treated 18crmo4 steel bar and pre machining 18crmo4 steel bar as following:

1)      Heat treatment of 18crmo4 steel

Oil quenching 18crmo4 steel / 18crmo4 normalizing steel / pre hardened18crmo4 steel / annealing 18crmo4 steel / stress relieving 18crmo4 steel / 18crmo4 qt steel / flame hardening 18crmo4 steel / 18crmo4 steel induction hardening / case hardening 18crmo4 steel / 18crmo4 oil quenched / austempering 18crmo4 steel / 18crmo4 steel water quenched / nitriding 18crmo4 steel /  milling 18crmo4 steel


After heat treatment, 18crmo4 steel bar can get better heat treated 18crmo4 steel properties, for example:

18crmo4 steel quenched and tempered properties:

Yield strength of 18crmo4 steel: 685MPa min

Tensile strength of 18crmo4 steel: 885MPa min

Elongation of 18crmo4 steel: 12% min

Reduction area of 18crmo4 steel: 50% min

Rockwell hardness of 18crmo4 steel: 32HRC max

Brinell hardness of annealed 18crmo4 steel: 197HB max

Vickers hardness of 18crmo4 steel hv: We can also guarantee the Vickers hardness based on your special requirements.

2)      Machining 18crmo4 steel:

knurling 18crmo4 steel / tapping 18crmo4 steel / grinding 18crmo4 steel / turning 18crmo4 steel / threading 18crmo4 steel / cutting 18crmo4 steel / drilling 18crmo4 steel / forging 18crmo4 steel / laser cutting 18crmo4 steel / reaming 18crmo4 steel / stick welding rod for 18crmo4 steel /  bending 18crmo4 steel / brazing 18crmo4 steel / straightening 18crmo4 steel / tg&p 18crmo4 steel / polishing 18crmo4 steel / cold drawing 18crmo4 steel

     After the machining, 18crmo4 steel can get precision size, various surface, better roughness, straightness etc. 18crmo4 steel can be used for axe, pins, knives, gun barrels, gears, bolts, washers, hammer, sword etc.

      As a Chinese steel bar professional manufacturer and supplier of more than twenty years, with complete produce and processing facilities, advanced testing equipments and big stock of steel bar, we can supply 18crmo4 steel bar with good quality, competitive price, short delivery time and personalized customization. We welcome old and new customers to inquire to us for technical questions and demands.
